Migrants have been paying 7 to 10 times the actual processing costs of visas for years, and many have been forced into destitution by extortionate fees. Now this government has increased them again. Migrants are not a magic money tree for politicians to keep exploiting. www.gov.uk/government/p...

The policy of enforcing political beliefs upon all foreign visitors is radically anti-American. It will sever us from international research networks and hobble our capacity to innovate—bedrock of American prosperity. Americans reject authoritarian rule.

My new paper with @guillaumeblanc.bsky.social is out as an NBER Working Paper. Demographic pressures have had lasting effects on the spread of diasporas. Malthusian migrations contributed to sustained improvements in living standards in Europe in the 19th century. www.nber.org/papers/w33542

What is the meaning of life? What is the meaning of life? What would you remember as bringing satisfaction, meaning, and purpose to your life? These are the modest questions that David Lagakos, Stelios Michalopoulos and I try to answer by "interviewing" over 1,400 Americans.

I am an economist. I may not have read Marx or Smith, but I did read "Potty Training in 3 Days" - properly historicizing my son's own methods of knowledge production.

This was one of the most interesting and creative papers I heard at #ASSA was definitely worth getting up early!

Léonard Wantchekon's autobiography is spectacular. What a life. Tortured by the regime in Benin in his student days. Years in prison. Escaped to Nigeria, then Côte d'Ivoire, from there to Canada. PhD at Northwestern, first job at Yale. Founder of the African School of Economics. Highly recommended 👇

If you're at ASSA, consider going to the ASREC session on Sunday 8-10am, where my co-author @romainwacziarg.bsky.social will be presenting our paper "Malthusian Migrations"!

Additionally, historical institutions and differential human capital investments contribute to the Nigerian case. Interesting example of how a comprehensive understanding of economic, cultural, and historical factors is needed to explain within country differences link.springer.com/article/10.1...

Turning off social media personalisation reduced toxic content exposure by 27%, BUT... Heavy consumers of toxic content just worked harder to find it - sharing what they found at higher rates & switching platforms. This suggests that algorithmic fixes alone won't solve online toxicity.

I wonder why Austin landlords suddenly became a lot less greedy.

You thought naming my paper "French" was a great idea? Me too! Until I found out Google Scholar can’t find it.

This is a great paper. With other papers, it's the solid beginning of a paradigm shift. Preference-based theories' paradoxes might be cognitive-based theories' regularities. Exactly as Saturn doesn't really invert its movement -- it just looks so from Earth. But we're not yet there. Small 🧵
